Description of problem (please provide a set of steps we can use to replicate the issue, and make as many as you need.):

Step 1: I created a new place maybe a week ago: https://www.inaturalist.org/places/national-botanical-garden I allowed the creation of check lists.

Step 2: There are observations prior to the creation of the place listed at Observations. There are observers as well under People. However, the checklist contains only the species that were uploaded after creating the Place.

Step 3: When will the older observed species appear on the checklist?
